Shell:

• Add --help/-h to help, alias, abbr, complete, config, prompt builtins
• help now passes argv so it can show per-command help
• cd - support with prev_cwd tracking (OLDPWD semantics)
• exit now warns and refuses if background jobs are running
• Ctrl+R incremental history search with live preview (type to filter, Up/Down to step matches, Enter accept, Escape cancel)
• doctor now runs real diagnostics (config file, HISTFILE size, no completions/abbreviations, AgentD on PATH)
• Default abbreviations: gco, ga, gc, gs, gp, gl, gd, glo, mkcd
• Default completions for: git, zig, npm, cargo, go, docker
• Subcommand tree support in CompletionCandidateSpec (--options arg)

Desktop:

• Ctrl+Shift+B focus previous pane
• Search overlay Enter jumps to matched scrollback line
• AgentD panel: warning banner, red text+label for pending writes, Enter action clarified in status bar
• Settings overlay: hint text updated to guide users

AgentD:

• Linux canonicalization guard warns once on stderr when realPathFileAlloc is unavailable (backstop silently fails open)

• docs/README.md: links CONFIG.md from hub
• docs/CONTRIBUTING_TOUR.md: smoke gate includes qa-tomorrow.ps1
